The problems haunting the world right now are a result of lack of love. The opposite of love is hate, so it follows that noone would look foward to see the happiness of any enemy and the next thing is to hurt the enemy. In calling "Love One Another" a new commandment Jesus' wish is a world where all people live in harmony by loving one another. If such a situation prevails there will be no murderers, adulterers or all perpatrators of all evils we see in the world today.
